Hazard Information

Chemical Properties
Barium azide is a flammable, crystalline solid which can be used or transported in solution.
General Description
A slurry of white crystals. When dry, a high explosive that easily ignited and quick to burn vigorously. Wetting reduces sensitivity to shock and heat. Generates toxic oxides of nitrogen when burned.
Reactivity Profile
BARIUM AZIDE, WETTED WITH NOT LESS THAN 50% WATER(18810-58-7) is a suspension or slurry of of an unstable solid in sufficient water to allow safe shipping and handling. May explode if allowed to dry out and then heated or shocked. Incompatible with strong oxidizing agents, strong reducing agents.
Air & Water Reactions
Highly flammable. Soluble in water.
Hazard
Explodes when shocked or heated.
Health Hazard
Some are toxic and may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
Potential Exposure
Barium Azide is used in high explosives.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a Medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce 340 Barium Azide vomiting. Do not make an unconscious person vomit. If weakness or fainting is present, lay the person down flat with feet elevated. See also First Aid section in “Barium” entry.
